dmesg needs /usr/adm/msgbuf

[ambiamber]

Hi,
There are multiple distributions with non-functional dmesg configurations, all of them are caused by /usr/adm/msgbuf being not there.

Example: 32V

# /etc/dmesg -

Jan  2 02:52
Namelist mismatch

/usr/adm/msgbuf is missing:

# ls -l /usr/adm/msgbuf
/usr/adm/msgbuf not found
# ls /usr/adm
dummy

Create it:

# touch /usr/adm/msgbuf

# /etc/dmesg -

Jan  2 04:25
Namelist mismatch

It has to be run twice after creating /usr/adm/msgbuf
as the first pass populates /usr/adm/msgbuf

# /etc/dmesg -
# 
There are no messages so no ("empty") output is displayed.
